Coal washing Coal that comes from a mine is a complex mixture of materials with a large variety of physical properties. In addition to the coal itself, pieces of rock, sand, and various minerals are contained in the mixture. Thus, before coal can be sold to consumers, it must be cleaned. The cleaning process consists of a number of steps that results in a product that is specifically suited to ...
heat treatment and has the advantages of rapid heating process, selective heating, and uniform heat distribution.20 The magnetic properties of the pyrite in the coal are enhanced, which is more favorable for the magnetic separation technology.21−23 For low-rank coal (lignite), microwave heat treatment can significantly reduce the water ...
The micronized-magnetite coal cleaning technology is based on widely used conventional dense-medium cyclone applications, in that it utilizes a finely ground magnetite/water suspension as a separating medium for cleaning fine coal, by density, in a cyclone. However, the micronized-magnetite cleaning technology differs from conventional systems in several ways: It utilizes significantly finer ...
Coal is dewatered after washing for efficient transport and use. Find Out More. The use of DMS magnetite is the most efficient technique for coal preparation and processing available. The DMS magnetite particles allow for greater control and a wider range of separation gravities.
Magnetite Uses - Education - Micrex Development Corp. The heavier specific gravity of magnetite aggregates allow a more aggressive backwash in the cleaning phase without loss of product, and because magnetite is magnetic it can be easily scavenged back from waste water streams for reuse Magnetite is an essential part of the "heavy media" process in coal,...
Magnetite Processing – Mining Equipment – Crusher Plant .. Magnetite (Fe3O4), like hematite (Fe2O3), is a form of iron ore. It is a benign and highly magnetic substance used primarily in steel manufacturing and coal washing. »More detailed

Coal mining industry. For the separation of coal from waste, dense medium baths were used. This technique employed the difference in densities between coal (1.3-1.4 tonnes per m³) and shales (2.2-2.4 tonnes per m³). In a medium with intermediate density (water with magnetite), stones sank and coal .

Quartz sand, silica sand, anthracite coal, garnet, magnetite, and other materials may be used as filtration media. Silica sand and anthracite are the most commonly used types. When silica is not suitable (e.g., in filters following a hot process softener where the treated water is intended for boiler feed), anthracite is usually used.
